FOOTWEAR APPLIANCE FOR SWIMMING.

Application filed December 9, 1924. Serial No. 754,862.

To all whom it may concern:

' Be it known that I, Eeenn'ros Man'rin'os Niooiiaas Konviisrc, a Dutch subject, residing at 103 Harrison Street, in the county of 6 London, V. C. I., England, have invented new and useful Improvements in Footwear Appliances for Swimming, of which the following is a specification.

The object of this invention is to provide a device to enable one to propel oneself in water at a reasonable speed.

In the accompanying drawings, Fig. 1, is a front view of the footwear appliance; Fig. 2, is an underside view of the footwear appliance.

The upper part of the footwear appliance is made of strong material such as an ordinary bathing shoe which is fixed on to a flat piece of wood A. This said piece of wood A is shaped to the outline of the sole and has underneath two wooden flaps B, longitudinally attached by means of hinges D, leaving a space in between. Within this space a longthin strip of wood C, is fixed to the sole member A, which prevents the flaps B, from turning on the hinges more than is required.

Eyes E, which turn pivotally with a spring movement upwards or. sideways like the eye of a collar-stud are fixed to the flap B, and when turn-ed up will engage small nails E on the flat sole member A, which are placed on both sides in the furthermost lateral position from the centre of the sole and thereby allow the flaps B, to be kept in level position, as shewn in Fig. 1, which will enable the wearer to walk in the appliances when on dry land.

I claim:

A footwear appliance having an upper part made of strong material, fixed on to a flat piece of wood shaped to the outline of the sole, said piece of wood has on the underside two flaps longitudinally attached by means of hinges leaving a space between said flaps wherein is secured longitudinally a thin strip of wood on to said piece of wood forming the sole member, cooperating parts secured at wide-st part of the sole members and adjacent part of flap for securing at will said flaps in horizontal position.
